Researchers created world's first sample of metallic hydrogen last month, and now it has disappeared.
However, the team has now announced that the sample has disappeared. In the year 1935, physicists Eugene Wigner and Hillard Bell Huntington claimed that hydrogen could exist in metallic form under high pressure.
Last month physicists from Harvard University in the U.S. had claimed to have successfully turned hydrogen into a metal - something researchers had been struggling to achieve for more than 80 years. Now, the metallic hydrogen, which was 10 micrometers in diameter, has disappeared.
Almost a century after it was theorized, Harvard scientists have succeeded in creating the rarest - and potentially one of the most valuable - materials on the planet.
The research team at the Harvard University lead by Dias and Silvera explained that a DAC (diamond anvil cell) was used for this objective that is capable of withstanding pressures as high as 495 GigaPascals. "We don't know", team leader Isaac F Silvera was quoted as saying by ScienceAlert. The new material was formed when scientists squeezed hydrogen so intensely that it changed to attain a metallic form, which according to scientists, might work as highly efficient electricity conductor at room temperatures. It is considered to be the holy grail of physics. Metallic hydrogen showcases superconductivity and scientists have been working on producing it for the last eight decades. They put it under an extremely high temperature of 495 gigapascals.
A sample of metallic hydrogen which was being kept in a lab at Harvard University had mysteriously vanished.
Understanding whether the material is stable is important, Silvera said, because predictions suggest metallic hydrogen could act as a superconductor at room temperatures. The advantages of this wonder material do outweigh the demerits it now faces on the various production fronts.
"It takes a tremendous amount of energy to make metallic hydrogen", Silvera explained. Silvera said that the diamond shattered like it was baking soda. Silvera and Ranga Dias, who led the research, said they were able to create this tiny sample by compressing hydrogens atoms in a diamond anvil.
According to the report published by Tech Times report that "Silvera and Dias are confident about their work and even urged other teams to try to reproduce the experiment as they have already shown how they achieved the high pressures and material in the lab". They have measured from the red, blue, green into the infrared. However, it seems that the diamond vice was destroyed in the process, which was discovered by measuring the pressure of the system with a low-pressure laser.
